The DR Silver Extra Life have nice tone, but are not the best coated strings I have played.

They have good tone, crisp sound and smooth feeling on the chording fingers. However, I can feel the coating in my picking fingers. I am primarly a finger picker with no picks and use the meat of the fingers on the strings and the strings feel slightly gritty on my picking fingers, like rosin on the strings. They do not feel smooth like naked non-coated nickel strings or like the Elixers do for me.

My chording fingers can't tell the difference, so you should not have this issue if you play with a pick. This being said, I have no opinion on how well the strings hold up to hard picking or if their coating wears well with rough playing.

For me, I will not be using these strings again but did not judge them harshly because most players use picks and will not have the issue I have.
